We use Zengrid framework from Joomlabamboo quite a bit - one thing it has is a shortcode to create column layouts.

I'm not sure if this is a K2 issue, or a Zengrid issue, but the latest update to K2 seems to have changed how it generates automatic meta data and has a conflict with the shortcode markup. The generated HTML does not get stripped and as result something like this appears in source:

<meta property="og:description" content="<div class="zen-row no-row-margin clearfix"><div class="zg-col zg-col-6">

This breaks the site layout as it leaves open div tags and meta tags

This never happened with previous versions of K2.

I did try re-ordering the K2 and Zen Shortcode plugins - it changed things, but didn't fix them. Can see here: thirdsundemo.com/test-item

I have a lot of sites using the Zengrid shortcode AND K2 so this presents a big issue for us. Any ideas?

Which plugin is rendered first?

Currently K2 is first. Putting the shortcode plugin first results in even worse result - basically breaks all CSS.

I can resolve this by manually setting the meta description - or if there are enough characters before the shortcodes, but still presents an issue and I'm holding off upgrading sites as I'm not sure what will happen with other shortcodes or plugins.

Do you have a DEV site were the shortcode plugin is first?

Now it is before K2: thirdsundemo.com/test-item

The plugin is still being executed in the metatag.
All tags are stripped in K2's metatags github.com/getk2/k2/blob/master/components/com_k2/views/item/view.html.php#L593

So I think you need to address this issue to the extension's developers.

For the time being, you can deactivate the meta tags

Thanks, I'm checking with Extension developer, too. However, this wasn't an issue with 2.7.1 - so what changed in regard to meta tags in 2.8.0?

It is most likely related to plugin event triggering.
K2 properly strips all HTML tags, so the issue might be related to when these plugins are being executed.

Hello!
I have the same problem i.e. on this site:
www.mathelike.de/klausuren-q11-q12/klausuren-q12-1/klausur-q12-1-001/loesung-aufgabe-1.html
Until there's a solution is it possible to reinstall v2.7.1 and where to get it?

Best regards
Christian
